undefined references

[Santosh Cheler]

Hi
I get the following error when compiling a class:

$gcj -I ../xerces.jar --main=Parser -o Parser Parser.java
/tmp/cc10KIkW.o: In function 'main':
undefined reference to 'Parser::class$'
collect2: ld returned 1 exit status.

Qstns:
1. What is the above error? how do I get rid of it?
2. Does this compile all the classes in xerces.jar and statically
    link them in the output executable? If yes, my executable will
    then be very big if I use large number of jar files.
3. Can gcj be used for production, ie., is it well-tested and stable?


thanks,
Santosh
